<p>
The rule is a polymorphic generator that acts as a named place-holder
capturing the behavior of a PEG expression assigned to it. Naming a
<a class="link" href="../../../abstracts/parsing_expression_grammar.html" title="Parsing Expression Grammar">Parsing Expression
Grammar</a> expression allows it to be referenced later and makes
it possible for the rule to call itself. This is one of the most important
mechanisms and the reason behind the word "recursive" in recursive
descent output generation.
